I almost did a FORTRAN subcontracting gig like this to translate an old but accurate simulation of a mechanical system to Python. I literally got a binder full of FORTRAN to start with, though eventually (to my great relief) the guy I was going to work under got me digital copies. Didn't pan out anyway, though, since he didn't win the contract.
